To all whom it may concern: I

Be it known that I, OTTO ALWIN SCHMIDT, a subject of His Majesty the German Emperof', residing at Ohelmsford, in the county .of Essex, England, have invented a certain new and useful Improvement in Ant1fr1c for its object to provide improved means for inserting the bearing in and withdrawing it from the housing, Heretofore bearings of this kind have been constructed by forming a spherical surface upon the outer race ring thereof and fitting same into a spherical seating, formed, either in a ring having a parts ofthe same sphere and adapted-to env plain outer surface adapted to be held in a cylindrically bored casing, or in a housing split either in one place or into two or more pieces Also ball thrust bearings are known in WhlCh the balls are supported sidewise by inner ringshaving outer surfaces forming gage with a correspondingly shaped outer incloslng ring having recesses to permit the inner rings and the balls to be inserted and withdrawn therefrom or alternatively portions of the peripheries of the inner rings have been cut away for this purpose.

According to this invention the housingis in one piece and portions of the spherical surface of its'seating or of the outer race ring of the bearing (which is of the self contained type) or both, are removed at opposite ends of a diameterof the housing or of the hearing so that when the latter is placed at right angles to the housing in the usual manner for the purpose of mounting or dismounting it, less force than usual will be required, and the danger of deforming the housing or cracking the ring will be considerably lessened. The housing may be made in the form of an external r ng having the same width as the race rings or narrower or wider if desired, or may be in the form of a pedestal or .hanger or any desired shape.

Dust washers or grease retaining rings are also provided. which are of special construction and render the bearing-dusttight with Specification of- Letters Patent. Application filed September 15, 1910. Serial No. 582,218.

Figure 1 is a front view of a single row ball bearing and housing constructed according to the invention and provided with dust washers, and Fig. 2 is a sectional elevation of same, and Fig. 3 is a part sectional elevation showing the bearing displaced in, the housing.

a is the housing having an interior spherical surface at b, and 0 are recesses or notches formed therein at opposite ends of a diameter.

d is the outer race ring of the bearing having a spherical .outer surface at c, said bearing being of the self contained type.

To remove the bearing from the housing it may be swung around at right angles and turned until it rests opposite the notches or recesses 0, when it can be easily removed.

It will be obvious that the pressure required to assemble or remove the bearing from-the housing a will depend upon the depth of the notches or grooves 0.

annular ringf forming a dust washer or grease holder, the outer edge of each ring coming lnside of the curvature of the housis formed with a curvature corresponding to that of the curved outer surface of the bearing, so that the rings may be inserted with the bearing into the housing a or removed therefrom, no screw or other fastenings being necessary, the curvature of the housing holding the rings-in position.

What I claim is a- In an anti-friction bearing, the combination of an annular housing having a spherical seat at a right angle to the diameter thereof, an outer race ring of less width than the housing and having an outer spherical surface adapted to be forced into contact spherical seat of the housing being recessed at diametrically opposite points to receive To enable the invention to be fully un- The above methods may be assistedby en holding against each face of the bearing an ing face b.
